Mark Steyn is a writer, political commentator, and cultural critic. He has written five books, including America Alone: The End of the World As We Know It, a New York Times bestseller.

Responding to critics who have called his America Alone "alarmist," Steyn defends the tone and central premise of his book. "This book is about...the larger forces at play in the developed world that have left Europe too enfeebled to resist its remorseless transformation into Eurabia and that call into question the future of much of the rest of the world, including the United States, Canada, and beyond."

According to Steyn, these forces include demographic decline in Europe, the unsustainability of the advanced Western social-democratic state, and civilizational exhaustion. Finally, in the face of these forces, Steyn offers what he believes America must do.
